Class TMatrixTransformNode

Unit

X3DNodes

Declaration

type TMatrixTransformNode = class(TAbstractGroupingNode)

Description

Transform children by an explicit 4x4 matrix.

This is an extension, not present in the X3D standard. See https://castle-engine.io/x3d_extensions.php#section_ext_matrix_transform . It is compatible with InstantReality, see http://instant-reality.com/documentation/nodetype/MatrixTransform/ .

	constructor Create(const AX3DName: string = ''; const ABaseUrl: String = ''); override;
	class function ForVRMLVersion(const Version: TX3DVersion): boolean; override;
	function TransformationChange: TNodeTransformationChange; override;

Description

Methods

	function DirectEnumerateActive(Func: TEnumerateChildrenFunction): Pointer; override;

	constructor Create(const AX3DName: string = ''; const ABaseUrl: String = ''); override;

	class function ForVRMLVersion(const Version: TX3DVersion): boolean; override;

	function TransformationChange: TNodeTransformationChange; override;

	procedure CreateNode; override;
Create node fields and events.

	class function ClassX3DType: String; override;

Properties

	property FdMatrix: TSFMatrix4f read FFdMatrix;
Internal wrapper for property Matrix. This wrapper API may change, we advise to access simpler Matrix instead, if it is defined (TODO: for now, some field types do not have a simpler counterpart).

	property Matrix: TMatrix4 read GetMatrix write SetMatrix;
